Application filed January 15. 1907; Serial No. 352,450,

To all whom it may concern:

Be it known that l, Gnonon WILLrs GonnAnD, residing at No. 1107 Sprucestreet, in the city of: Philadelphia, county of Philadeh hia and Stateof Pennsylvania have inp i v 7 vented certain new and usefulImprovements in Safety Car Signaling Devices, whereof the folliowing isa specification, reference being had to the accompanying drawings.

My invention relates to improvements in signaling devices of thatgeneral class employed in connection with cars and other vehicles forsate guarding passengers boarding or alighting from the car or othervehicle.

The principal-object of my invention is to provide meansfor preventingthe conductor or other person in charge of the car from ringing the bellin the usual manner whenever there is anybody standing upon the step orwhen any one is boarding or alighting from the car. In the preferredform ofiny invention this is accomplished by obstructing the clapper toprevent it from striking the bell; whereas, in a modified form, the

bell cord is gripped intermediate the bell and the person attempting toring it, whereby the cord is rendered inoperative to move the clapper.

A furtherobject of my invention is to furnish signals whenever anybodyis upon either 01' all of the steps, or boarding or alighting from thecar.

A still further object of the invention is to indicate to the motormanor person controllingthe motive power, that some one is upon the step.

My invention comprises the various novel features of construction andarrangement hereinafter more defii'iitely specified and claimed.

in the accompanying drawings, Figure i,

' shows the preferred form of my invention applied to the ordinarytrolley car. Fig. 11, is a diagrammatic view shown'ig the location. ofthe various devices constituting this form of my invention amt-thecircuits for control ling them. Fig. ill, is a section through one oithe car steps and circint'closers. Fig. IV, is a plan ol the bell anddevice for obstructing the clapper. F1 V, is an end elevation of themechanism siown in Fig. IV. Fig.

* V1, is a diagrammatic view showing the location of the various devicesconstituting the mod fied form of my invention and the circuits forcontrolling them. Fig. V11, is a detail View of'the cord clamping devicein normal position. Fig. VIII, shows the clamping device when the cord,has been gripped and pulled tov one side for transmitting a signal.

In said drawii s,1, is a gong orbell, the. clapper 2, of which, isadapted to be operated by the cord 3,- in the usual manner. it. is. tobe understood that obviously any other .kind of audible signal may besubstituted;

for the one shown, without departing from my invention.

The device for preventing the clapper 2,

from striking the gong 1, to be hereinafter more fully described, isadapted to be operated whenever a passenger is standing upon one of thesteps or boarding or alighting from the car. The current for operatingthe obstructing device is obtained from the sup ply which provides thepower for operating the car, said current enterin at 5, and leav ing at6, and having a suitable resistance 7, interposed, which may consist ofa coil or lamps as desired.

1 At'each step8, 9, 10, and 11, is located a circuit closer. In Fig. ll,only two circuit closers 1 3, and 15, are shown, but it is obvious thatone may be connected from each step. A switch 16, may be interposed forthe purpose of cutting out the system if desired. Located at each end ofthe car, at a point convenient to the motorman, are the lamps 17, 19,and buzzers 18,. and 20. The lamps may be colored or otherwise.

Referring to Fig. Ill, for the construction and operation of the circuitclosers;-40, is the side guard of the step, 41, is the riser, and i2, isthe tread. means of suitable pivots connected witli the side guards 40.At the front of the tread and below the same, is a suitable spring formaintaining this end of the tread in its upward positit'in, so that aweight, as of a person, boarding or alighting from the car, will beeffective to move the circuit closer. I have shown a plunger 43, pressedby a spring 44, inclosed in a casing 45, although any other suitablemechanism may be readily employed. At the rear of the tread 4-2, is anarm 46, attached thereto, and having an upward extension 47 providedwith a bridging contact 48. Around the upward extension 47, is a coiledspring 70, which normally.

The tread is hinged by.

. tends to keep the bridging contact 48, from the stationary contacts49, and 50, mounted upon a suitable insulating support 71. Thesecontacts are immersed in abath oil oil '72, contained in a casing 73.depressing the tread l2, raises contact 48, to engage contacts 49, andObviously other forms of circuit closers may he substituted if desired,but I have found this form to be safe and reliable.

Referring to Figs. IV, and V, for the detailed construction of thedevice for obstructing the bell clapper, 80, is a solenoid housed in asuitable casing 82, adjacent to the gong 1. The plunger 83, of thesolenoid is provided on its outer end. with a brass or similar tip84, ofsullicient length to bridge from the clapper 2, to the contact 85. Theinner end of the plunger 83, is surrounded by a spring 86, which normallr tends to keep the plunger in retracted position, shown in Fig. IV./Vhen. the solenoid so, is energized the plunger tip 84, passes betweenthe clapper and gong thereby striking the contact 85, and alsopreventing the clapper from striking the gong. The clapper 18 connectedto the conductor 90, arnl when pulled by the cord 3, contacts with thetip 84, closing the battery circuit. 2

The operation ol this form of my invention is as follows, referencebeing bad to Fig. lI:---l.t may be assumed that a passenger is standingupon the stop 1], thereby depressing the tread 42, closing the circuitcloser 15, in the manner above described. The current then enters at 5,and llows through the switch 16, solenoid 80, conductor 87, solenoid S1,conductors 88, 89, circuit closer l5, conductors 91, 92, lamp ll),conductor 98, lamp 1?, conductor 94, resistance 7, and leaves at point(3. Tllhcreupon the lights 17, and 19, are lighted, giving a visualindication that one of the steps is occupied, and both solenoidplunger-s are drawn out as above described, and their tips obstruct theclappers. When the cord is pulled so as to move the clapper, at theright hand cud ol Fig. H, said. clapper comes in contact with the tip ofsolenoid 81, closes circuit o'l bale tery 100, and humor 18, is sounded;but the clapper will not strike the gong, owing to the obstructingplunger tip. The person upon the step must move oil before the gongsignal can be given.

Referring to Figs. Vl to v'ill, a modified Form of my invention isshown, in which the bell cord is clamped by tho clmnpiug device 4, to beliorcinal'tcr 'moro'l'ully described. The current 'l'or operating thevarious dcviccs is obtained l'rom the supply which provides the powerl'or opcraliug the car, said current entering at 5, and leaving at 3,and having a suitable resistance 7, iulcrposed between the source ofsupply and the devices to be operated. fit each slop is. .l, l(), and .ll, is located a circuit closer 112, 12;,

Said weight in,

. erases mannr alreodf described. A switch 16, may be mterposed'neareach .circult closer for the purpose/cf allowing that circuit l xcloserto be cut out if desired, Located at Joints convenient to the :motormanare the amp 17, and lluzier 18. These are'shown f as duplicated at tileother end of. the car, but

this is merely a matter of convenience. The lamp 17, may becolored orotherwise.

Referring to Figs. VII, and. VIlI, tor the detailed construction of thcclamping device, 26, is a solenoid secured to a pivoted plate 57,andhavin plunger 58. Upon the plunger 58, is a small roller 61, uponwhich the bell cord 3, rests. Above the bell'cord and mountedupon-opposite sides of the plate 57, are two rollers 59, and (ll). Whenthe plunger of the solendid is drawn up the bell cord is tightlyclen'rped between the rollcrs 58, 59, and 6U as shown in Fig. VIII. Theplate 57, is pivoted tothc frame 62, which is adapted to be secured tothe car in any suitable manner. Attached to the l'ramo 62, but insulatedtherefrom, are two stationary contacts 32, and 34. Secured tolhc plate57, in a. position to engage the stationary contacts 32, and 34-, is thebridging contact 33. The movable and.

the other side of the frame for the purpose of making the devicereversible and easily adapted. to dillercnt locations in the car.Located on each side'of the plate 57, are springs es, w rich normallykeep the plate plate to its normal position whenever it has been pulledto one side, as shown in Fig. Vlll. The tension of these springs may bevaried by means ol thc thumb screws 64-. The clamping device should belocated close to the gong or other signal to be sounded, yet enoughslaclc'cord should be lelt between the two to enable the cord to begripped and pulled to one side to close the circuit through contacts 32,33, and 34, without operating the clap mi of the gong. The operation ofthis modihcation is as follows :--For crmvcnicnce ol description, it maybe assumed that a passenger is standing upon the stop l l therebydepressing the tread 42, closing the circuit closer l.-" ,iuthema1uicrabove described. The currcntthcn enters at .3, and flows through theresistance 7, couductors 21, 22, switch 16, circuit closer l5,

comluctors 23, 24, lamp 19, conductor 25, solenoid 26, conductor 27,lamp 17, conductors 28, and 29, and leaves at the point (i. 'lhorcupon,the solenoid 26, becomes energized drawing up its core-'58, and clampingthe cord 3, between the rollers 5%), (l0, and (51. At the same time themotorman is notified by the lighting o'l' lamp 17, that some one isstanding upon the stop or is boarding or alight lug from the car. Shouldl4, and 15,"arlapte, l to be operated in the stationarycontacts areshown duplicated on lil an upright position and tend. to return the theconductor or any other person attem t to ring the gong 1, at this time,by pulling t 1e cord 3, the solenoid and its supporting plate would bemoved to one side as shown. in'

Fig. 1H, thereby closing the circuit through the contacts 32, 33, andCurrent there upon flows through conductors 30, 31, contacts 32, 33, and34, conductors 35,36,.buzzer l8, conductors 37, 38, and 29, and out at6.

From the above description, it will be seen that while a passenger isboarding 'or alighting from the car, the bell cord is tightly gri ped toprevent the gong from bemg sounced in the usual manner. each time thecord is pulled a buzzer is sounded giving a signal to themotorman.

I do not desire to limit myself to the pre cise details of constructionand arrangement herein set forth, as it is obvious that'variousmodifications may be made therein without departing from theessentialjeatures of my invention.
